Satellite Collision Avoidance Patents: Top Companies & Trends 2026
Filing growth compares 2021 (1,776 records) with 2024 (1,278) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 71,101 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape maps 71,101 published records retrieved under a search string combining satellite collision avoidance with the broader triad of satellite, collision and avoidance terms. The scope spans 2015 through the mid-2026 data cut-off, capturing both dedicated space-traffic patents and a much larger volume of adjacent filings in wireless networking, vehicle control and radar positioning that share claim language with collision-avoidance systems.
Because the search string is broad by design, the dataset mixes narrow space-domain-awareness filings with general collision-avoidance patents drawn from automotive and telecom portfolios. Readers should treat the IPC composition below as a guide to where claim density actually sits, not as a pure count of dedicated satellite hardware patents.

Filing trends and technology composition
Two views of the same 71,101-record corpus: filings by year, and the IPC subclasses those records fall under. Because a single record can carry several classes, the composition shares sum to well over 100% of the record total.
Filing trend, 2017-2026
Filings rose from 1,248 in 2017 to a peak of 2,148 in 2020, then eased to 1,278 by 2024 — a 28% decline over 2021-2024. The drop to 122 in 2026 reflects the incomplete year and the roughly 18-month lag between filing and publication, not a sudden stop in activity.
Technology composition by IPC subclass
H04W (wireless communication networks) and G08G (traffic control systems) lead at 6.5% and 6.2% of all records respectively, ahead of G05D (control of non-electric variables) at 5.2% and G01S (radar, sonar and positioning) at 4.4%. B60W, H04L, G06F and G01C each cover a further 2.9%-4.4% of records, showing that collision-avoidance claims are distributed across communications, control and data-processing disciplines rather than concentrated in one hardware class.
Shares are the percentage of the 71,101 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Device and methods for satellite control and collision avoidance using artificial intelligence
The disclosure describes a smart satellite device that collects sensor data on its physical environment, runs that data through a deep reinforcement learning program to produce steering instructions, and manipulates the satellite's panels to achieve an optimal collision-avoidance trajectory. The stated purpose is to address the space debris problem directly through autonomous, learning-based trajectory control rather than ground-commanded manoeuvres.Filed by an individual inventor rather than an established aerospace assignee, illustrating that AI-driven autonomous collision avoidance is still open territory for new claimants.

Three patterns stand out once the raw counts are put in context: where the field is genuinely concentrated, where filing momentum is heading, and how the technology mix maps onto adjacent disciplines.
The core is dense, the tail is long
The top 5 ranked assignees together account for 33.0% of all 71,101 records in scope, and the top 10 reach 41.0%. That leaves the majority of filings spread across a long tail of single- and few-filing entrants, which is where freedom-to-operate analysis needs the most granular work.
Post-peak cooling, not collapse
Filings peaked at 2,148 in 2020 and declined 28% from 1,776 in 2021 to 1,278 in 2024, the last year that can be treated as complete. Recent-year assignee momentum figures show sharp year-over-year drops at the leading filers, but publication lag means 2025-2026 counts will keep filling in.
Communications and coordination outweigh pure sensing
Wireless networking (H04W) and traffic control systems (G08G) each cover a larger share of the 71,101 records than radar and positioning (G01S) or navigation/gyroscopes (G01C). Collision-avoidance claim space is as much about data exchange and coordination logic as it is about detection hardware.
US-centric filing with modest multi-jurisdiction spread
The United States receives far more filings than any other office in this dataset, with Europe (EPO) and WIPO (PCT) as the next largest routes. Australia, Canada and the United Kingdom each show a few hundred filings, indicating that most applicants have not yet pursued broad multi-jurisdiction protection for this technology.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to space-domain awareness & debris: satellite collision avoidance patent landscape, with the prior art for and against each one.
Where to take this analysis
The counts and rankings on this page are a starting point for deeper diligence, not a substitute for it. Three lines of follow-up work make the most of this dataset.
Run freedom-to-operate on the long tail
With 41.0% of records held outside the top 10 filers, most of the claim space sits with entities that file rarely. A targeted FTO search against specific claim language is more useful here than a landscape-level view.

One assignee leads clearly with 9,424 records, ahead of the fifth-ranked assignee at 1,980 and the tenth at 846. The top 5 ranked assignees together hold 33.0% of all 71,101 records in scope, and the top 10 reach 41.0%, meaning the majority of filings still sit with a long tail of smaller filers. Many of the largest filers are communications and semiconductor companies whose portfolios overlap with collision-avoidance claim language rather than dedicated space-systems specialists.
Filings rose steadily to a peak of 2,148 in 2020, then declined 28% from 1,776 records in 2021 to 1,278 in 2024, the most recent year that can be treated as complete. Counts for 2025 and 2026 appear lower still, but that reflects the roughly 18-month lag between filing and publication rather than an actual drop in activity. The safest read is a post-2020 cooling from a filing surge, not a collapse in interest.
Wireless communication networks (H04W) and traffic control systems (G08G) are the two largest IPC subclasses, each covering roughly 6% of the 71,101 records, ahead of control systems (G05D) and radar/positioning (G01S). This indicates that a large share of the claim space concerns coordination, data exchange and control logic rather than pure sensing hardware. Because records can carry multiple IPC classes, these shares are not mutually exclusive and sum to more than 100% of the record total.
The under-claimed branches identified in this dataset include autonomous conjunction-assessment algorithms, multi-satellite swarm de-confliction protocols, and onboard reinforcement-learning trajectory planners, all of which sit outside the dense wireless and traffic-control core. The representative AI-based trajectory-control filing in this corpus was filed by an individual inventor rather than an incumbent, which supports the idea that autonomous, learning-based collision avoidance is not yet locked up by any single large portfolio. A first claim in this space would do well to specify the sensor-to-decision pipeline precisely, since broad autonomy claims are more likely to run into prior art from adjacent robotics and vehicle-control filings.
The United States receives far more filings than any other office in this dataset, at 13,995, followed by Europe (EPO) at 2,714 and the WIPO PCT route at 1,832. Australia, Canada and the United Kingdom each show a few hundred filings, well behind the top three. This pattern suggests that most applicants have prioritised US protection first and pursued broader multi-jurisdiction coverage more selectively.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
